Yabu - always a solid meal. 6 ppl, ordered mushroom egg udon, nabeyaki udon, soboro don, chawanmushi, karage, tataki, ankimo, and yellowtail collar. came out to about $70 without tip. all delicious and great for a cold day.
Place Yuu - tried the regular sashimi plate and nabeyaki udon, chawanmushi. For $60 for 2, I'd rather go to Hide and get really full or even Echigo. The sashimi plate was fresh though, and the squid really impressed - almost had the amaebi consistency and texture - best squid i've had. the yellowtail was excellent as well.
